Abstract
Disclosed are interconnection patterns and semiconductor packages including the same. The interconnection pattern comprises a first dielectric layer, a first interconnection pattern in the first dielectric layer, a first barrier layer between the first interconnection pattern and the first dielectric layer, a first top surface of the first barrier layer located at a level lower than that of a second top surface of the first dielectric layer and lower than that of a third top surface of the first interconnection pattern, a second barrier layer on the first barrier layer, the second barrier layer interposed between the first interconnection pattern and the first dielectric layer, a second dielectric layer on the first dielectric layer, the first interconnection pattern, and the second barrier layer, and a second interconnection pattern formed in the second dielectric layer and electrically coupled to the first interconnection pattern.
